Roll up cable (also known as reel up cable), often referred to as cáp cẩu, is a special cable designed for frequent retraction, winding, and movement conditions. Its core is high flexibility, strong tensile strength, bending resistance, wear resistance, and oil resistance. It is used for power and signal transmission of large equipment such as ports, mines, and cranes.
This type of product is also often used in electrical connection scenarios that require frequent movement or retraction, such as stage lighting, mobile device power supply, temporary power supply for construction sites, etc. The design of coiled wire and cable aims to improve the convenience and safety of use, while reducing cable wear and clutter.
From a technical perspective, reel wire and cable usually use high-strength, wear-resistant insulation materials and conductor materials to ensure that they are not easily damaged during frequent winding and unwinding processes. At the same time, they also have excellent electrical performance, such as low resistance, high insulation resistance, etc., to ensure the stability and safety of current transmission. In addition, the winding structure of the drum wire and cable is carefully designed to ensure that the cable can be smoothly wound and unfolded during the retraction process, avoiding jamming, winding, and deformation.
Core structure of drum cable
1.Conductor: Multi strand ultra-fine oxygen free copper wire (VDE 0295 CLASS 5/6), with good flexibility and low resistance.
2.Insulation layer: TPE, EPR, PVC or rubber, resistant to bending and heat.
3.Tensile strengthening layer: Kevlar fiber/galvanized steel wire rope, capable of withstanding tension and torsion.
4.Shielding layer (optional): woven copper wire/aluminum foil, resistant to electromagnetic interference.
5.Outer sheath: PUR (polyurethane, high-end), nitrile rubber or modified PVC, wear-resistant, oil resistant and anti-aging.
Key characteristics of drum cable
● High flexibility and bending resistant drum cable: capable of withstanding tens of thousands of winding cycles, with a bending radius of approximately 8-12 times the outer diameter of the cable.
● Strong tensile drum cable: equipped with built-in tensile elements, with a tensile strength of 5-15kN, suitable for long-distance deployment and retraction.
● Environmental tolerance: -40 ℃ to+100 ℃, wear-resistant cable, oil resistant cable, acid alkali resistant cable, UV resistant cable.
● Stable transmission: power/control/signal hybrid design, suitable for integrated transmission of encoders, communications, etc.
Application scenarios of reel cables
In terms of application scenarios, coiled cable have a wide range of applications. In the field of stage lighting, they can conveniently provide power for lighting equipment and move flexibly with the adjustment of stage layout. In terms of power supply for mobile devices, coiled wire and cable can ensure that the equipment does not lose power during movement, improving work efficiency. In temporary power supply scenarios such as construction sites, coiled cable can quickly establish a temporary power supply system to meet construction needs.
● Port machinery: container quay cranes, yard cranes, gantry cranes, and ship loaders.
● Mining/metallurgy: crane, excavator, stacker reclaimer, smelting drum system.
● Lifting equipment: bridge/gantry crane, electric hoist, lifting platform.
● Other: Stage equipment, intelligent storage, sewage treatment equipment, mobile cable car.
